@ur invention relates to metallic'sashes for holding the glass of windows and show cases.,

and particularly to division and corner bars for holding large and heavy sheets of platey glass.

@ne of the objects ofthe invention i" Jrhe ,non

provision of improved. iand simplified sashr nembers, readily andcheaply'forined from slm-t metal, and which .largely ob'viate 'the het,

danger of bre karfe of the @dass due to thel feat res of advantage, some of which, with the roregoing will be set forth in the following description of the our invention which is illustrated in e drawaccompany' and forming partv of the speciication. lt is to be understood that we do not'limit ourselves to the 'showing made by the said drawings and description, we

2 may adopt variations of the preferred form within the scope of our invention as set forth the claims.

Referring to the drawings:

Figure l is a horizontal' sectional view taken thru a vertical division bar( Figure 2 is a side elevation of the'tie bar elementl of our invention, the direction of the view being indicated by the arrow 2 of Figure l.

Figure 3 is a plan view of the tie bar, the direction of view being indicated by the arrow 3 of Figure 2. v

Figure l is a horizontal sectional view thru a corner bar embodyingour invention. p

ln terms of broad inclusion our sash com# prises a stationary sash bar conveniently of lzl-shaped section and having secured on' the inside thereof a bracket. Our invention chicles the manner in which this bracket is secured to the bar. The stationary'sash bar engages one side of the glass, and on the other side of the glass is the adjustable sash bar. Fasteningr the two together is a. tie bar interlocked in the adjustable sash bar andextendacross the bracket to which it is clamped bya screw. In order to prevent the tie bar from moving when the clamping screw is seated upon it7 the underlying portions of the bar are corrugated'so that .the head of the screw nnbeds itself in the corrugations. The

y stable sash bar. It maybe desirable to interpose a shoe plate between the stationary sash bar and the glass and in this case we previas an integral tongue on the bracket engageable with the shoe to secure it in place.

ln detail, our invention comprises a verti-` cal sash bar member 2, preferably of U shaped section as shown yin Figure vl. The

Vedges of this member are turned back to provide glass-engzugfing beads 3. At intervals in the length of the sash bar apertures are provided for the mounting of the brackets-4. rl`hese brackets are formed with an aperture 6 surrounded by an vannular flange 7, and are n permanently secured to the sash member by expanding the annular flange in the sash apertures, as shown in Figure v1.

Tie bracketis formed to provide a seat 8 about midway between the side walls the sash bar and at the free end is bent to form a leg 9 engaging the side wall of the sash bar. `A rib 10 gives the required stiffness to the bracket structure.

, On the opposite side of the glass 11 is the adjustabler sash bar l2 having inwardly turned glass-engaging flanges 13 on each side. Means are provided for fastening the adjust able sashbar to the stationary sash bar, and such means comprises a tie bar placed opposites-ach bracket thruout the length of the bars. The tie bar is formed at one end with. a slot lli, bordered by corrugations l5, and this lend of the tie bar is adapted to over- 455 tie bar itself is formed from a` single piece voi' sheet metal, portlonsat one end being lie that portion of the seat of the bracket 8f directly underneath the aperture 6. A screw 7.6 having a head 17 is threaded into the bracket concentric with the aperture 6. and accessible therethru, so that separate holes inthe ll-bar for this purpose are unnecessary.

Preferably the underside of the screw head is cone-shaped, and the adjacent portion of the bracket surrounding the screw is complenientary inform, so that when the screw is tightened down upon the tie bar, the corrugations are forced into the conical depression the seat by the coned screw head, which also iinbeds itself in the corrugations. The corrugated end of the tie bar provides a
